description
Appearance and leaf
Magnolia floribunda grows as a tree and reaches heights of up to 20 meters. The gray bark is smooth. The young twigs, which have a diameter of 2 to 3 mm, have a pressed, white hairy bark ( trichomes ).
The alternate leaves arranged on the branches are divided into a petiole and a leaf blade. The 1 to 1.5 (rarely up to 2.5) cm long petiole is compressed, hairy white. The leathery simple leaf blade is 7 to 12 (rarely up to 14) cm and a width of 2 to 4 cm narrowly ovoid-elliptical, narrowly ovoid or narrowly obovate-elliptical with a broadly wedge-shaped to rounded blade base and a pointed to tail-pointed upper end. The underside of the leaf can be frosted and has pressed, long, white hairs. The upper side of the leaf is deep green and shiny. The middle nerve usually has white hairs and eight to twelve lateral nerves on each side. The dense and thin network nerves are slightly raised on both leaf surfaces. The scars that remain after the stipules fall off are at least half the length of the petioles.
Flowers and fruits
The heyday of Magnolia floribunda ranges from February to April. The flowers are on 3 to 7 mm long short shoots. These short shoots have fine, silvery hairs and are covered with one or two bracts that soon fall off . The flowers are narrow, elliptical and slightly curved, they are white and hairy yellow on the outside. The 11 to 13 bracts are spoon-shaped to inverted-lanceolate and end with a short tip, they are 2.5 to 3.5 cm long and 0.4 to 0.7 cm wide. On the central axis of the flower, which is about 5 mm long, there are 10 to 14 stamens and the carpels . The stamens extend beyond the anthers with a long tip. The carpels are composed of the 2 mm ovary and the 2 mm long, densely silvery hairy pistil .
The wrinkled fruit becomes 2 to 6 cm long. The fruits ripen in August and September. The individual ripe carpels are round with a small tip, they reach a diameter of 0.6 to 1.5 cm.
Chromosome number
The number of chromosomes is 2n = 38.
